EFFECT OF COMPOUNDING CONDITIONS ON MECHANICAL-PROPERTIES OF GLASS-FIBER-REINFORCED POLYAMIDE-6

Glass fiber-reinforced polyamide-6 (GFPA-6) was compounded using a HYP ERKTX46 twin screw extruder with three different types of screw segmen ts (rotor segments, kneading disc segments and turbine segments). Base d on the neural network regression analysis, we investigated the effec ts of compounding conditions, such as screw configurations, screw rota tion speed and production rate on mechanical properties, such as tensi le, flexural and impact strength of GFPA-6. It was found that the mech anical properties of GFPA-6 changed in different ways with compounding conditions (screw rotation speed and production rate), depending on t he type of screw segments. It was also found that the rotor segment ex hibited good mechanical properties in wider ranges of compounding cond itions than the kneading disc segment and the turbine segment, probabl y due to its mild and uniform mixing capability.
